Project for the weekend: We have some new cat pens in a location exposed to wind. We have some polycarbonate sheets to fix over the mesh panels.
Ideally, they should be easily removable in hot sunny weather. I can visualise a small plate with a threaded centre that could be fixed to the frame of the pen. Then it would be easy to remove the sheets, leaving the small plates in place.
If the mesh is strudy[rigid] then drill two holes one each side of verical in sceral locations and use sturdyvwire[frncing] through one hole around the verical bar and back out and twist the ends together to secure panel to mesh
4 per panel should suffice.
On our dog kennels, we use a combination of 'penny' washers,fibre/rubber washers, galvanised bolts with wing-nuts. When the sheets need removing for cleaning or ventilation, its a simple case of unscrewing the wing-nuts.
If you have access to a Wickes store, then check their range of free literature for fixing, installing, using etc on their range of products. B&Q and Homebase also provide this free leaflet service, but their literature is limited.
Perhaps should have also mentioned, that if you have metal bars or angle iron framing, hook bolts with wing-nuts are ideal for ease of use. hook bolts are getting more hard to obtain, unless you get them from a specialist supplier.
